| Abstract: | This paper describes the methods of calculation of the original sedimentary rate for sandstone, conglomarate, and mudstone. The deduction of the formulae in this paper is based on the concept of "fragment volume in rock" and the function between porosity and deepth during the compaction. The sedimentary rate calculation formulae are as followings.The two formulae above are used to SN8717 # Denglouku Formation and Zhaoshen 2 well of Yaoja Formation, in which the authors describe how to get parameters A, B(or a,b) by regression.and discuss how to use these formulae practically. At last, the authors prove that these formulae are applicable to any kind of normal sedimentary rocks. |
